Question

question 3
what is the approximate diameter of an atom?
10^{-10} cm
10^{-10} m
1 cm
10^{-15} m
10^{-15} cm

Explanation:

Atoms are extremely small. The unit of measurement for atomic size is typically meters. Through scientific research and measurement, it is known that the approximate diameter of an atom is on the order of \(10^{-10}\) meters. \(10^{-10}\) cm is much too small (\(10^{-10}\text{ cm}=10^{-12}\text{ m}\)), 1 cm is way too large for an atom's diameter, \(10^{-15}\text{ m}\) is the order of magnitude for the size of a nucleus (not the whole atom), and \(10^{-15}\text{ cm}(= 10^{-17}\text{ m})\) is also far too small for an atom's diameter.

Answer:

\(10^{-10}\text{ m}\)
